Les problématiques de sureté nucléaire passent par l’évaluation des installations existantes et notamment des enceintes de confinement. L’enceinte est un double sarcophage en béton armé. Elle constitue une barrière protégeant à la fois le réacteur d’une agression extérieure mais aussi protégeant l’extérieur d’une éventuelle fuite en cas d’accident. Le bon fonctionnement de l’enceinte est assuré lorsqu’elle remplit ses fonctions de résistante et d’étanchéité. L’évaluation de ces deux fonctions se fait notamment par le suivi de l’état de fissuration de l’enceinte.La fissuration du béton est associée au développement de micro-fissures qui apparaissent lorsque les contraintes locales du matériau sont dépassées. Il résulte de ces micro-fissurati...
